PURPOSE: This study aimed at reporting the long-term oncological outcomes of robotic partial nephrectomy (RPN) for renal cell carcinoma (RCC). METHODS: Data from all consecutive patients who underwent RAPN for RCC from July 2009 to January 2012 in three departments of urology were prospectively collected. Overall survival (OS), cancer-specific survival (CSS) and disease free-survival (DFS) were estimated using the Kaplan-Meier method. Prognostic factors associated with CSS were sought in univariate analysis. The log-rank test was used for categorical variables and the Cox model for continuous variables. RESULTS: 110 patients were included with a median follow-up of 64.4 months [95% CI = (61.0-66.7)]. Median age was 61 years (29-83) with 62.7% of men and 37.3% of women. Median RENAL score was 6 (4-10) with elective indications accounting for 95% of cases. Out of 27 patients (24.5%) who experienced peri-operative complication, 12 patients (10.9%) had a major complication (Clavien-Dindo grade ≥ 3). The TRIFECTA achievement rate was 52.7%. Three patients (2.7%) experienced local recurrence and seven patients (6.4%) progressed to a metastatic disease. 5-year OS, CSS, DFS were 94.9, 96.8, 86.4%, respectively. In univariate analysis, no pre/peri-operative characteristic was associated with DFS. No port-site metastasis was observed and there was one case of peritoneal carcinomatosis. CONCLUSION: In this multicenter series, long-term OS, DFS and CSS after RPN appeared comparable to large series of open partial nephrectomy, with no port-site metastasis and one case of peritoneal carcinomatosis.
